water at once.
To avoid print quality problems, DO NOT touch the shaded parts shown in the illustrations.
Note
• Be sure to seal up the drum unit tightly in a suitable bag so that toner powder does not spill out of the unit.
• Discard the used toner cartridge according to local regulations, keeping it separate from domestic waste.
If you have questions, call your local waste disposal office.
e Unpack the new drum unit.
CAUTION

in properly, the green lock lever will lift automatically.
